Description

[Detailed Description of the Invention] The present invention relates to the structure of a plastic hubcap that is fitted and fixed to the rim of a vehicle tire, and in particular to a clip that presses against the rim and holds the hubcap so that it does not come off. Regarding support structures.

BACKGROUND ART Hubcaps of this type have been known for a long time, and because they are highly decorative, they have attracted attention as a type of car accessory.

By the way, this type of hubcap is fixed by simply fitting and crimping the rim of a vehicle tire, so even if the rim deforms or sudden braking occurs, it will not be removed from the rim. While it is necessary to make the crimp structure strong so that it does not come off or rotate,
From a manufacturing standpoint, it is required that the structure be simple and that assembly is easy.

The basic purpose of the present invention is to provide a hubcap that can satisfy both of the above requirements, and in particular has excellent clip mounting and fixing properties.

Therefore, in the present invention, a protrusion defining an axial insertion hole is provided protruding from the inner wall of the outer peripheral part of the wheel cap body, and a locking hole is recessed in the bottom or side surface of the insertion hole. The tip of the metal plate is bent upward to form a spring part, and the base of the plate is provided with a spring piece that comes into contact with the upper surface of the insertion hole with a spring force, and the engagement hole is provided in the insertion hole. The basic feature is that a clip is provided with a locking part that irremovably engages with the stop hole in the axial direction, and the clip is fixed by being inserted into the insertion hole from the axial direction. .

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments.

In FIG. 1, 1 is the outer periphery of the plastic hubcap main body, 2 is a protrusion with a rectangular cross section that protrudes axially inward from the inner wall 1a of the outer periphery, and 3 is the inner wall 1aK of the outer periphery approximately from the end surface 2a of the protrusion. An insertion hole with a small aspect ratio reached at 'i!', 4 is a locking recess provided at the center of the bottom of the insertion hole, 5 is a hole for punching a mold to form the locking recess 4, and the insertion hole is 3, the metal clip 60 base 6a is forcibly inserted from the axial direction P and is fixed.

This clip 6 has a base portion 6a having a width equal to the width of the insertion hole 3, and is continuously curved upward to form a spring portion 6b. When inserted, a locking portion 6C that fits into the locking hole 4 and is irremovably engaged in the axial direction protrudes downward, and the base 6a
Two spring pieces 6d are provided on the husbands on both sides of the body, which are raised diagonally upward in the rearward direction with respect to the insertion direction.

The height of the rear end of these spring pieces 6d relative to the base 6a is set to be appropriately higher than the height of the insertion hole 3, so that each spring piece 6d is placed on the top surface of the insertion hole 3 when the clip 6 is inserted. It is designed so that it can come into contact with the spring force.

Further, the tip of the spring portion 6b of the clip 6 is cut diagonally upward at the center thereof, and is attached to the rim portion (second
A claw portion 6e is formed to be bited into the wheel cap (see FIG. 9), and on both sides of the claw portion 6e, there are legs that extend over the upper surface 2b of the protrusion 2 of the hubcap body when the clip 6 is inserted. 6f and 6f are provided diagonally downward.

When the base 6a of the clip 60 having the above-mentioned configuration is forcibly inserted from the axial direction into the back wall of the insertion hole 3 provided on the wheel cap body side, the base 6a as shown in FIG. The spring piece 6d contacts the upper surface 3a of the insertion hole 3 with spring force and presses the entire base 6a against the lower surface of the insertion hole 3,
The locking recess 6C of the base 6a that fits into the locking hole 4 is the locking hole 4.
Maintain the mated state so that it does not come out.

Note that the legs 6f, 6f provided on the spring portion 6b have a slight gap above the upper surface 2b of the protrusion 2 in the free state before fitting the hubcap to the rim 9 of the vehicle tire. It is a good idea to set the wheel cap so that it is in the correct position so that it does not act as a spring when installing the wheel cap.

1. After attaching the clip 6 to the hubcap body as described above, when the hubcap is pushed into the rim 9 of the vehicle tire from the axial direction, the spring portion 6b of the clip 6
When the claw portion 6e of the wheel cap contacts the rim 9, the spring portion 6b is elastically deformed, and the wheel cap is completely pushed in.
Due to the elastic deformation of the spring portion 6b, the lower ends of the legs 6f, 6f abut on the upper surface 2b of the protrusion 2, and the spring portion 6b
.

6f.

As a result, the spring rigidity of the spring portion 6b increases accordingly, and the claw portion 6e that bites into the rim 9 is supported with strong spring rigidity, so that even if the rim 9 is deformed or the vibration of the tire occurs, the wheel cap will not be damaged. It can provide strong pressure bonding properties that will not fall off.

Regarding the locking structure of the base of the clip, as shown in FIG. Corresponding to the recess 4', upright walls 8c, 8c on both sides of the base 8a of the clip 80
A locking portion 8d formed by bending the
, 8d are provided, and when the clip 80 base 8a is inserted into the insertion hole 3', the locking parts 8d, 8d are inserted into the locking recesses 4', 4.
It is also possible to have a structure in which the clip 8 is engaged from both sides to prevent the clip 8 from coming off in the axial direction.

In addition, in the example shown in FIG. 3, the spring piece 8e to be formed on the base 8a is formed by folding back the base 8a.
The base portion 8a of the clip 80 is held within the insertion hole 3' by the spring force e.

Further, as the claw portion 8f provided on the spring portion 8b of the clip 8, a large number of triangular raised projections 8g, . . . , 8g may be provided vertically and horizontally on the spring portion 8b, as shown in the drawing.

Moreover, in place of the projections 8g, . . . t8g as described above, although not specifically shown, a large number of claws may be provided in the width direction.

In this way, the biting force of the claw portion 8f against the rim 9 can be increased, and the claws can be made to bite into different parts of the rim 9, which improves the biting ability against the rim 9. It can be made into something.

As is clear from the above description, in the present invention, the flat base of the clip is provided with an engaging portion and a spring piece, and the base is inserted into the insertion hole defined in the rectangular parallelepiped protrusion. The engagement part can be held in the locking hole of the insertion hole with a spring piece so that it cannot be removed, making it easy to install the base into the insertion hole, and also securely hold the base in the insertion hole. This allows the locking structure to be made more complete.

In addition, since the spring part of the clip is formed with a leg part extending to the upper surface of the protrusion, when the hubcap is attached to the rim part of a vehicle tire, the claw part can be supported by the spring part and the leg part. , the spring rigidity can be made strong, so the wheel cap has extremely good crimping properties.
It can be made into L.
